My neighbor from above love to use granite stone bowl to knock some food/spice for cooking. I bought the small blender for this particular neighbor and issue solved.

I had similar experience as well, when feel it come from my above floor but actually is 2 level above mine. Complaint is useless, try talk to them nicely and understand why it happen so often.

Anyways living in high rise you can face a lot this problem unless you staying in landed which have lesser problem
